The power frequency withstand voltage test voltage between the secondary windings and the box (grounding) should be 2kV, which can be replaced by a 2500V megohmmeter to measure the insulation resistance test;
The frequency pressure-resistant test voltage between the secondary windings and their to the box (ground) should be 2kV, which can be replaced by the 2500V mega-table measuring insulation resistance test.
